Question
Download Solution PDFIn the context of 3D Computer graphics, which of the following statements is/are correct?
(A) Under perspective projection, each set of parallel lines in the object do not stay parallel in the image (except those that are parallel to the viewplane to start with).
(B) Applying a perspective transformation in the graphics pipeline to a vertex involves dividing by its 'z' coordinate.
(C) Perspective transformation is a linear transformation.
Choose the correct answer from the options given below:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 1.
Key Points
- Under perspective projection, each set of parallel lines in the object do not stay parallel in the image The lines converge to the middle of the projection at a single point. Points of intersection of converging lines with the screen plane generate the projected image on the screen.
Hence statement I is correct.
- Applying a perspective transformation in the graphics pipeline to a vertex involves dividing by its 'z' coordinate.
Hence statement II is correct.
- Perspective transformation is a non-linear transformation.
Hence statement III is incorrect.
